摘　　要：对大量不同结构类型平面框架进行地震弹塑性时程分析,得出地震响应时程曲线;根据曲线上的最大值绘出弹性及弹塑性反应谱,并拟合其反应谱计算公式,比较了它们之间的异同。参考现行抗震规范提供的反应谱计算公式,将不同结构类型的反应谱进行规准化,并与规范计算公式进行比较,结果表明现行规范反应谱计算方法比较粗糙,不能很好反映不同结构类型的地震反应特点。The earthquake elastic and elastoplasticity time interval analysis to many plane frames were analysised. The lastic reaction spectrum of these structure was gotten. The elastic reaction spectrum formula was proposed. The reaction spectrum of these different structure was compared. According to response spectrum formula with which the present earthquake resistance standard provides. Compared with standard, it can be found that the present standard response spectrum computational method is quite rough. It can not response the different structure type＇s earthquake response.
